USB to Serial Converters

I have purchased 10 ATG 6410 laptops I am in the process control industry and require Serial communications. I have tried a variety of vendors USB to Serial converters and am having fits getting them to work with this particular laptop. We are talking to Programmable Logic Controllers, Variable Frequency Drives, and other field equipment with serial communicaitons.

Re: USB to Serial Converters

Handshake problems or data errors can be caused by a number of issues including USB Port power management which

I suggest you turn off.


There are several vendors of USB to Serial Adaptors that use the Prolific PL2303 chipset.

I don't recommend other vendors for these devices because WHQL drivers are few and far between.

There are compeditors like FTDI USB Serial whql.  ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

Re: USB to Serial Converters

You probably would have been better to buy a laptop with an ExpressCard slot and used ExpressCard to serial converter card.

Did you look at the ratings for these USB to serial converters on Newegg?
